Can some one please help??

yellowvanman thanks for advice, here i go again:

first section (50m@22A) = 4.4x22x50/1000 = 4.84 volts

second section (30m@12A) = 4.4x12x30/1000 = 1.58 volts

third section (40m@5A) = 4.4x5x40/1000 = 0.88 volts

overall voltage = 4.84+1.58+0.88 = 7.3 volts

This calculation gives the same result as in post #27, so there is more than 1 way to get the correct answer.
